iSCSI SAN for Windows
iStorage Server Ultimate

iStorage Server is an IP SAN solution that allows you quickly export existing storages such as disk images, physical disks, partitions, CD/DVD-ROMs, tapes or any other type of SCSI based devices and even a variety of popular CD/DVD images to its client machines, which delivers immediate benefits allowing storage to be consolidated, virtualized and centrally managed. iStorage Server also provides RAID-1 (mirror) feature, which allows you create two devices for mirror backup, the mirror devices can be local image files or remote iSCSI devices. iStorage Server has been added support for Microsoft Virtual Disk File (VHD) and VHD snapshots at the recent release.

Compares between KernSafe iSCSI SAN and XTremeSAN
  • Provides fast replication synchronization and failover feature, that allows you to create a high-availability iSCSI SAN by using two or more iSCSI targets.
  • Provides RAID-1 (Mirror) feature that allows you to create two image files for mirror backup, image file can be local file or remote iSCSI device.
  • Provides a built-in iSCSI virtual disk emulator. It exports existing disk images to mounted iSCSI disk drives on the clients. All the clients share the same contents.
  • Provides security disks for each client, optionally each client can use its own disk which use his/her CHAP password encrypted.
  • Provides a built-in iSCSI CD/DVD-ROM emulator which exports existing DVD-ROM ISO images to mounted iSCSI DVD-ROM drives on the clients. This prevents the original DVD-ROM media from possible physical damage or loss, so it also allows client machines without optical drives and allows storing DVD backup data on a single server.
  • Provides extremely fast ISCSI RAM disk drives for temporary data storing on network.
  • Provides volatile and persisted COW protection feature that automatically create snapshots for each initiators with virtual write permission.
  • Provides Generic SCSI device, it allows you map generic SCSI devices to your initiator, such as USB Storage, Tape and Optical Scanner.
  • Provides a network-bridged method. It exports an existing partition, disk, CD/DVD-ROM to clients as a virtual iSCSI drive.
  • Provides read and write caching, which uses memory on server as cache to improve data transfers speed and response time.
  • Provides CHAP user authentication mechanism.
  • Provides client's IP address authentication mechanism with additional security.
  • Active Directory-integrated local and remote management console.
  • Provides iSCSI Target portal address management, which allows you to make iStorage Server to be able to work behind the firewall.
  • Provides simple and banausic user management tool, to manage CHAP users.
  • No restrictions on disk capacity, total number of hard disk installed, number of CPUs or CPU cores, Ethernet ports or the amount of RAM.
  • Supports CDP/Snapshots that are compatible with Microsoft VSS (Volume Shadow Copy Services) snapshot, volume cloning and incremental backups with unlimited number of rollback points.
  • Supports Microsoft Virtual Hard Disk (.VHD) and VHD snapshot, which provides instant and point in any time snapshot feature.
  • Supports multiple connections per iSCSI session, which allows you to create Round Robin, Weighted Paths and so on.
  • Supports x86 and x64 machines.
  • Supports 64-bit LBA, providing more than 2TB of disk space.
  • Supports sparse image file on NTFS file system. It allows the size of disk image file only depend on its content used.
  • Supports any features on file system, such as in NTFS, a image file can be encrypted, compressed, or shared with other computers.
  • Supports a variety of popular CD/DVD image formats, such as: .iso, .bin, .mdf, .cdi, .b5i, .nrg, .ccd, .sub, .img, .raw.
  • Supports a variety of partition table format, such as the MBR, GPT.
  • Provides “Hold and Update“ mechanism that allow you can update data file from initiators to targets.
  • Fully Supports SCSI-2 Reserve/Release.
  • Fully Supports SCSI-3 Persistent Reserve.
  • Fully Supports VMWare Platform and VAAI (ATS, ZERO and XCOPY) interface.
  • Fully Supports Citrix XenServer.
  • Fully Supports open-iscsi on Linux.
  • Fully conforms to the latest iSCSI Standard 1.0 (former Draft 20).
